- Specification of Letters Patent.

Patented March 24, 1908.

Application filed October 29, 1907. Serial No. 399,660.

To all whom it may concern:

Be it known that I, ERNEST A. EASTMAN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented an Improvement in Last-Demonstrators, of which the following description, in connection with the accompanying drawings, is a specification, like otters on the drawings representing like parts.

My present invention is a device for demonstrating or designating t0 the ob server the position which the axis of the foot will be compelled to occupy by a given heel, being a species of the invention covered generically in my copending application Ser. No. 386,730 filed August 2, 1907, where the invention, broadly considered, is more fully described, said application and my present application both avin reference also to my invention set forth in atent No. 857,552 of June 18, 1907.

In carrying out my present invention I provide, in connection with a sole member (or piece cut like a sole pattern or innersole), an upwardly extending part shaped to conform exactly to the heel, said part being limited in its extent to the heel portion so as to leave the entire sole-part free and unrestricted for the p'ur ose of visually indicating to the ob-, server-t e position which the given heel. will compel the axis of the foot to occupy in a I shoe constructed according to the pattern or outline of said sole-part. This upwardly extending portion may either be secured permanently to the sole-part of the demonstrator or detachably, the former rendering the demonstrator better ada ted for demonstrating in connection with t e actual foot of an interested party, while the latter is more convenient for visually comparing diflerent sole patterns or styles of lasts. In the drawin s, in which I have show two preferred em odiments of my invention,

. Figure 1 is a plan view of one form of the demonstrator, Fi s. 2 and 3 are plan views of another form of t e demonstrator; Fig. 4 is a fraemen tary view in side elevation of the em odiment of my invention shown in Figs 2 and 3, looking at the rear or heel end thereof; and Fig. 5 is a cross sectional view on the line 5-5 Fig. 1..

As illustrated in Figs. 1 and 5, the demonstrator consists of a base or back 1 which.

may be of Wood cardboard, celluloid, metal or any suitable durable substance, to which is secured a plate 2 preferably of hard metal, such as steel, so as notto wear appreciably in use, and sole arts 3 3 herein shown as two in number. he part 1 is flat so as properly to display the parts 3 3 ,when placed thereon, and t e part 2 is accurately cut awa in its front edge so as to provide a vertical wa 14 conforming with the utmost nicety and exactness to the standard heel contour or outline to the sole-parts 3 3 and for receiving the same as clearly shown in Figs. 1 and 5'. A thumbscrew or other securing means 5, herein shown as having a threaded end 6 securing into a ferrule 7 in the base] is provided for centrally clamping the sole-parts 3 3 which for this purpose are centrally apertured at 8.

In the construction shown in Figs. 2 and 3 formed in a metal or other plate 2 se arately secured on a base or back 1 I form t e same directly on the sole-part as indicated at 9, where I have shown a vertical ortion, extending upwardly ap roximate y coextensively with the usual s oe counter, and. bent under the sole-part 3 3 about its heel contour or outline, where it is secured permanently to the soleart as indicated by dotted lines at 10. referably each sole part contains an axis line 11 marking the center line of the last as explained in my above mentioned Patent No. 857,552, and in the form of my invention shown in Fig. 1 the base 1 also contains the same line as indicated at 12.

In use let it be supposed that it is desired to demonstrate the advantages of my particular kind of last, i. e., the last of my patent last mentioned, over the same style, of crooked last provided with the ordinary or old-kind of heel, the two bottom-patterns of the respective lasts are reproduced in correspondingly shaped sole-parts, the one show mg my patented last being indicated at 13 and the other at 14 in the drawings. The operator or user then places one sole-part on the other so that the vertical wall 4, Fig. 1, or walls 9, Figs. 2 and 3, compel the heelparts of the two different styles of sole-parts to coincide one above the other, the result being that the forward portions of the two sole-parts are caused to assume the relative 4O s'ponding shoe actually on strator directlyg on the foot of an interested arty, sim ly y'shoving the demonstrator, ig. 2, or F ig. 3, against the sole of the foot,

' thereby causing t e wall portion 9 to embrace the heel of" the foot.

This causes the demonstrator to assume, with relation to the foot, the actu al position of the 'shoe, which is shown more accurately in Fi 1, the form of sole-part in Fi 2 pro ecting eyond the foot on the'forwar inside part, whereas the form shown in Fig. 3 follows the shape of a normal foot without projecting at any portion thereof. Instead .of merely indicatin' the relative position of the center line, as y the bar of my above mentioned application, in my present embodiment of the invention I provide the entire sole-part and show tangibly and visually how the different heel contours or outlines compel said sole-part to swin to one side or the other and hence the tren of 90 the corresponding last or shoe, the center line thereof being indicated by the marked line 11 and 12. This illustrates to the unskilled the effect which the shifting of the heel outline or contour laterallyin one direction or the other will have on the position of the foot in the shoe when made, thereby enabling the average wearer of shoes to appre ciate such variations 'or difierences in the lines of the heel prior to etting the .correlns foot. Having described my invention, claim as new, and desire to secure by Letters Patent, is,

"1. A device for the purpose set forth, com- 4b prising means showing the outline of a forepart, and means showing the outline of a eel part, including means for showing varying positions of the heelpart outline with relation to the forepart outline consisting of a plurality of sole-parts having their forward portion arranged at varying directions withv relation to the same heel contour, and means for ,compelling the corresponding heelpart contours to substantially coincide when said sole-parts are superposed.

2. A device for the purpose set forth, comprising a sole-part whose forepart terminates free and unrestricted 'at its edge-boundaries which have the peripheral outline of the inwhat I eeaeie sole of a shoe, and a vertical wall conforming in outline to the contour of the heel portion of said sole-part.

' 3. A device for the purpose set forth, comrisin r a sole-part having the eri )heral outme o ceiving said sole-part provided with a vertical wall conforming in outline to the contour of the heel portion of said sole-part.

4. A device for the-purpose set forth, comprising a sole-part having the peripheral outine of the insole of a shoe, a separable wall conforming ';t0 the outline of the heel part thereof, and means for detachably positloning said heel-part in exact engagement with said well.

5. A device for the purpose set forth, comrising a sole-part having the peripheral outine of the insole of a shoe, a vertical wall conforming in outline to the contour of the heel portion of said sole-part, and means for indicating visually the axis line of said sole-part with relation to said wall and heel portion:

6. A device for the purpose set forth, consisting of a plurality of sole-parts all having the same heel outline but in different relative positions with relation to the fore-parts thereof, and'means for'automatically ahning said heel outlines when said sole-parts are placed on top of each other.

7. A device for the purpose set forth, consisting of a plurality of sole-parts all having the same heel outline but in diiferent relative positions with relation to the foreparts thereof, a plane base for supporting said soleparts, avertical wall secured at one end of saidbase conforming to said outline, and

means for positioning all of said sole-parts so as to make their heel outline coincide against said wall.

8. A device for the purpose set forth, consisting of a plurality of solearts all having the same heel outlinq but in iflerent relative positions with relatibn to the foreparts thereof, all of said sole-parts being similarly ap-. ertured in their heel-parts, a base for supporting the heel ends of said sole-parts, a

vertical wall projecting from said base, and

clamping means arranged to extend through said apertures to .clamp said sole-parts to said base with their heel outlines coinciding against said wall.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
